Prevention & Follow-Up
Store grains and dry goods in airtight containers to cut off spider beetles' food supply. Regularly clean dust and food debris from cabinet corners, drawer bottoms, and under bookshelves. Don't let old cardboard boxes and clutter pile up—they make perfect hiding spots. Keep rooms well-ventilated and dry to discourage spider beetle breeding. If you find spider beetles, deep-clean all storage areas and vacuum dust and crumbs out of every crack and crevice.
